The European statistics agency Eurostat also revised growth in the first quarter, from 0.4% to 0.5%.

Also on Tuesday it was announced that German imports and exports had both reached record levels.

Boosted by the continuing weakness of the euro, exports rose 2.4% to €103.4bn ($115.5bn; £75.1bn) in July, the federal statistics office Destatisestimated, after adjusting for seasonal and calendar effects.

Imports also rose, but not by as much, meaning the trade surplus grew to a record €25.0bn.

The upward revision to GDP for the first quarter is a result of the inclusion of Ireland, which had not been counted in earlier estimates.

The Irish economy grew 1.4% in the first three months of 2015, compared with the previous quarter, making it the fastest-growing eurozone country.

With the Irish figures not yet included, the fastest-growing eurozone member in the second quarter was Latvia at 1.2%.
